Thanks, Miss Bliss! I was similarly inspired by the lovely lunches in bento communities that I have seen and decided to diversify from sandwiches! :)

I've found the Lock n Lock boxes to be of a good size for lunches, as well as being sturdy and air/watertight. I do like my other containers as well, especially the traditional Japanese ones (click on the 'bento' tag/category)

I use the 'suction method' to get the sauces into the little containers. Squeeze the bottle to get the air out, maintain the pressure and dip the opening into a small saucer of soy sauce/olive oil/dressing. When you release your fingers, the sauce will get sucked into the container. I use the same method to clean out the containers: suck soapy water into them, shake them a bit and then squeeze the water out, and then do the same with clean water. I tend to use the same containers for the same sauces so it's not crucial for them to be clinically clean since the flavours and smells won't mix.
